think about how much money you want to spend on this ??? then check out who has a small chamber head that is why i said AFR they have a very nice head trick flow my be ok i can say never had a set in my hands .i still would go with the line up of AFR .dart .profile brodix .getting it right chamber cc will help getting past 9.5 cr if this is going to be max race engine i would want to be at better then 10to1 . here are some pistons to look at wisceo pto39h3 11.8 at 104 cc and pto39h6 both same dome just bore size and a forged piston . KB 9949 this is a 4023 alloy and would use a stock 366/427 3.760 crank and would be 11.3 cr with a 112 cc head or a KB 361 thats a hyper 390 alloy and used a 4.000 crank that can be over 427 has to do with what bore you end up at and is 11.1 CR with a small chamber head 95cc that may limt your head pick for chamber size to find so any thing more out there in a stocking shelf piston any thing more you are looking at custom pistons could be in your future and thats about $ 950+ a set at that point use a 4.000 crank you get more CID and will help build some CR .this is why many do not play with the 396/402 power can be made some pistons are not out there like the bigger bore engine when all said and done the 454 block start looking good. with a 454 and what crank/parts you end up with can yield a 427 to 511 with a stock block. tell them it a 396 they will never know trust me on this.. it been done
